TRACTIVE RESISTANCE ASSESSMENT OF SEEDING-MACHINE WITH COMBINED COLTERS

Abstract

The priority direction of scientific research in the field of agriculture of Kazakhstan is the development of new technologies for the cultivation of crops, such as minimal and zero [1, 2]. The implementation of new technologies requires the development of new effective means of mechanization: seeders and tillage machines [3]. The proposed work is aimed at the development of efficient technical means for the implementation of new technologies. In the proposed development, for the first time in world practice, a combination of disc and chisel coulters, disc and cultivator feet was used on a direct seeding drill. An analysis of studies of the use of various working bodies showed that the smallest value of traction resistance of the drill from the working speed of the unit at different tillage depths is observed for the drill with coulters according to the chizel-disk-diesel scheme. Moreover, the discrepancy between theoretical and experimental dependencies is insignificant. At the same time, with an increase in the working speed of the unit, the theoretical and experimental dependences for a seeder with serial lap coulters increase intensively, on average, by 1.5 times. The same dependence of traction resistance on the speed of the unit. A similar dependence of fuel consumption on the depth of seeding and the speed of movement of the unit. Traction resistance of a prototype of a seed drill with openers chizeldiscs-chizel with a seed embedding depth of 4 cm and a working speed of 10 km / h is 4.888 KN and in the prototype seed drill with openers the paw-paw with the same indicators - 7.638 KN, the serial seed drill - 9.33 kN, that is, the pulling resistance of prototypes with combined coulters is 1.22-1.9 times lower than with a serial seeder. Similar ratios of traction resistance of the prototypes and the serial seeder with a seeding depth of 7 cm and a speed of 10 km / h.
